Question

Which of the following is most likely to have the greatest concentration of smooth endoplasmic reticulum?

a. a cell that secretes enzymes

b. a cell that destroys pathogens

c. a cell that makes steroid hormones

d. a cell that engages in photosynthesis

Short answer

A cell that makes steroid hormones is most likely to have the greatest concentration of Smooth Endoplasmic Reticulum.

Step-by-step solution

Explanation

A cell having only SER can not secrete enzymes as it is the function of the Rough Endoplasmic Reticulum. So, option a is incorrect.

Destruction of the pathogen has nothing to do with Smooth Endoplasmic Reticulum. Hence, option b is wrong as well.

The Smooth Endoplasmic Reticulum is responsible for hormone and lipid production not in photosynthesis. So, option d is wrong too.

The Smooth Endoplasmic Reticulum has steroid secreting cells, these cells synthesize steroid hormone by using cholesterol as a precursor. Thus, option c is correct.

Conclusion

A cell making steroid hormones will be having the large number of SER as they help in hormone production.
